Switches And Amplifiers Ensure Fast, High-Res Video Distribution

Teaming up, the AD8175/6 triple 16x9 crosspoint switches and AD8145/6/7/8 differential amplifiers deliver 500 MHz of bandwidth and support UXGA and QXGA resolutions in large video displays. The AD8175 (G=+2) and AD8176 (G=+4) switches feature a slew rate of 1800 V/µs and support sync on common-mode and sync on color operation. Operating differentially and/or single-ended from a ±2.5V or +5V power supply, the devices consume 3.5W. The AD814x family of differential amplifiers is reportedly the industry's first line of triple differential drivers and receivers to achieve a full-power bandwidth of 550 MHz. The ability to send and receive RGB and sync signals over CAT5 cable is integrated on chip, enabling video distribution systems to maximize resolution. Price for either the AD8175 or AD8176 is $95 each/100, with full production quantities set for April and July, respectively. The AD8145/6/7/8 differential amplifiers are sampling now with prices ranging from $2.89 to $3.09 each/1,000. ANALOG DEVICES INC., Norwood, MA. (800) 262-5643.
